Be it known that I, HERMANN LOTHAR WAR- dale, Addiscombe Grove, East Croydon, in

Appliance and Advertising Device; andl d o hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art vto which it appertains to make and use the same.

This invention relates to a contrivance which way-stations on which are printed a large numthe names of railway-stations, the igures inthe line of railway included inthe column of diihculty -is encountered `in accurately deterfsistance of oneor both index-lingers and then with an undue eiiort of concentration and liatable. To eliminate this difliculty and fault, Imount the time-table in a frame within which isprovided meansfor guiding the ends or' a mains always parallel to one line. The strip being lifted to 'a position immediately below the name or a station and held there, the eye will lbe guided along the horizontal edge of the strip and the time required to be known immediately observed. There are additional features oi' advantage associated with the invention, to which reference will presently be made.

The accompanyingdrawings show a method of construction whereby theinvention may be carried into practical eect.

In the drawings, Figure l is a front elevation of the time-table and frame within which it is mounted. Fig. 2 is a sectional side elevation taken through the line 2 2 on Fig. 1. Fig. 3 is a plan. Figs. 4, 5, and 6 are enlarged views showing details of the construction, Fig. 5 being a front view of the upper right-hand Serial No. 142,060. (No model.)

` corner of the frame with a portion removed tol exhibit the interior. Fig. i is a section through the line 4 4 of Fig. 5, and Fig. 6 is a section through the line 6 6.

For the purpose of rendering a clearer illustration the scantlings of the frame in Figs. 1 2, and 3 are exaggerated relatively to the area of the time-table which is exhibited.

` On account of the small print which is per- Jforce adopted in order to exhibit a very large number of trains on a sheet of limited area it is necessary that the moving strip should maintain its parallelism with considerable accuracy and move with freedom even if the moving force is 'applied at one end and not in the center of its length. This is eliected'by securing each of the' two ends of the strip a to an endless chain b, which at the top is wrapped arounda sprocket-wheel c, which has teeth adapted tosuit the pitch of the chain t, and at the bottom around a pulley CZ oi' plain periphery.`

The two wheels 'c are identical in size and in the number of teeth, and they are secured to a spindle e, 4mounted in bearings f f in the upper portion or' the frame. By means of this mechanism the strip can be caused to move with great lfreedom and remain always parallel' to the top and bottom edges of the frame. The ends of the strip are guided in a narrow slit g, formed between the front surface of the frame, and a plate li, which is fastended to the front at the top and bottom. Behind the plate 7a a space is'left for the edge of the time-table.

. YThe time-table should preferably be printed on a thin card, which can be inserted through a slit k, formed in the Atop of the frame. After adjusting the card with its printed lines parallel to the movable strip, a finger and thumb recess m being formed in the upper surface of the frame for the purpose, the card is secured by pinching its upper edge tightly` between the front lath n, which has' suliicient flexibility for the purpose, and the back o. This is eifected by two hinged clamps p p.

When the clamps are lifted, as shown in Fig. 6, the slit k is wide enough for the easy insertion of the time-table card, and when the clamps are pressed tightly down the wedge- IOO shape end draws the lath @toward o by pressing on the edge of a plate q, which is fastened ,by screws to the lath n.

To assist the observer in seeking the required information, the edge of the strip is divided into spaces which correspond to the columns of train times, and the spaces carry numerals like those at the head of the columns which signify the number of the train. In this way it will be easy to identify any train.

The motion of the chain will permit of the association of another device for affording information consisting of an endless traveling band r, which is secured to the chain at a suitable portion of its length and wrapped around a semicylindrical surface s at the top, which shrouds the sprocket-wheel, and around a similar'surface at the bottom, which shrouds the pulley d. By this contrivance the band will be caused to move with the chain each within one side of the frame. sition a glazed window t is provided on each side of the frame, and on the band are displayed advertisements or any kind of information thought desirable-as, for example, the names of and particulars relating to hotels inthe various places on the line of railway to which the time-table relates. The band should be vso adjusted relatively to the chain that the names of hotels or other matter which at any moment appear at the window should relate to that place on the railway whose name is most adjacent to the moving strip. rlhe remainder of the surface of the frame may also be utilized for advertisement purposes or for giving other information by providing grooves u u at the front edges, as shown in the several figures, 4into which printed cards or plates may be slid endwise. At the bottom right-hand corner is shown a secret device for preventing the card from being withdrawn by unauthorized people who are ignorant of the device. A plate c has a slotway w formed in it, into which the head of a screw fits. By this means the turned-over edge of the plate c may be withdrawn sufficiently to permit the card to be extracted or one inserted. When the plate is home in place, its turned-over edge will cover the' edge of the card and no means for extracting it will be apparent.

The movement of the strip a may be still further utilized to effect, by lifting the strip, the automatic electric illumination of the time-table at night during the few moments when it is being consulted and the extinguishing of the light by breaking the circuit when the inspection is completed by letting the strip a descend by its weight and press on the At some suitable popush a' of any electric switch and break the contact between the end .of the spring y and the contact-.plate 2.

I claim-- l. A device for facilitating a reference to a mounted time-table consisting of the timetable, a frame, a spindle to which sprocketwheels are secured at the two ends thereof, two endless chains each embracing a sprocketwheel and a pulley and extending along and Within one of the sides of the frame and a strip which at each end is secured to the chain and is moved therewith in such a way as to remain always parallel to one line.

2. A device for facilitating a reference to a mounted time-table consisting of the timetable, a frame which is adapted to clamp the edge of the time-table and secure it in position, a spindle to which sprocket-wheels are secured at the two ends thereof, two endless chains each embracing a sprocket-wheel and a pulley and extending along and within one of the sides of the frame and a strip which at each end is secured to the chain and is moved therewith in such a way as to remain always parallel to one line.

3. A device for facilitating a reference to a mounted time-table, consisting ofthe timetable, a frame, a horizontal spindle mounted within the upper edge of the frame to which sprocket-wheels are secured at the two ends thereof, two endless chains each embracing a sprocket-wheel and a pulley and extending along and within the vertical sides of the frame, a horizontal strip which at each end is secured toa chain and a band carrying advertisements which travels with the chain and exposes changing portions bearing information relating to the locality the name of which is at the instant adjacent to the strip.

4. A device forfacilitating a reference to a mounted time-table consisting of the timetable, a frame and a strip which is adapted to be moved within the limits of the frame in such a way as to remain always parallel to one line, and an electric switch which is adapted to be spring-pressed to close the circuit of an adjacent. electric lamp and when pressed by the otherwise unsupported weight of the strip to cause the circuit to be broken.

In testimony whereof I have hereunto set my hand -in the presence of two subscribing witnesses.
